Aerial Lingus

Ireland is one of the few countries of the world to have an extensive MMDS network. MMDS — or Multichannel Multipoint Distribution Service — is ‘cable TV without cables’, using microwave transmissions between 2 GHz and 3 GHz. Each subscriber has a small aerial which usually comprises a broadband dipole, a reflector, and a down converter. The first two pictures show two types of MMDS receiving aerial. Since MMDS can only be received if there is perfect line-of-sight to the transmitting aerial tall masts are common, as the third and fourth pictures show.
